What the defaults give
Level 9, shuttle 4 estimates a VO2 max of 45.1 ml/kg/min, rated good.
The calculation is 3.46 × (level + shuttles ÷ 8) + 12.2, the Léger shuttle-run regression.
The formula
VO2 max = 3.46 × (level + shuttles ÷ 8) + 12.2
The level number and the shuttle number are one continuous scale: each level has a fixed number of shuttles, so reaching level 9 shuttle 4 is written 9.4-ish in the regression. Dividing the shuttle count by 8 puts it in the same units as a full level. The 12.2 is the intercept — the VO2 max the regression predicts for someone who stops at the very first stage.
Worked examples
Level 9, 4 shuttles → 45.1
Level 4.5 → 29.5
Level 18 → 76.2
Level 9, 2 shuttles → 44.2
Level 9, 8 shuttles → 46.8
Most of the movement comes from the level, not the shuttle count: six extra shuttles within the same level are worth 2.6 ml/kg/min, while one full level is worth 3.46. That is why the level number needs to be accurate — a mistake of one stage is a bigger error than any shuttle miscount.
What VO2 max means
It is the maximum volume of oxygen your body can use per kilogram per minute during hard exercise, and it is the single best laboratory measure of aerobic fitness. The beep test estimates it from running speed at exhaustion rather than measuring gas exchange, so it carries roughly a 10–15% error against a treadmill test.
Reference bands for adults sit near 40–45 for a moderately trained man and 33–38 for a woman of the same age; endurance athletes reach the 60s and 70s. Rating labels vary by source and by age, so compare your own number over time rather than against the label.
Getting a usable result
The test is only valid if you stop when you can no longer reach the line in time, not when it becomes uncomfortable. Pace the first levels — going out too fast is the most common reason for a low score. A 20-metre course, proper turning technique and the same surface each time make repeated tests comparable.
Repeat every six to eight weeks rather than weekly; aerobic adaptation is slower than that, and the test itself is hard enough to affect training for a day or two.
Frequently Asked Questions
What VO2 max is level 9 on the beep test?
About 45.1 ml/kg/min at level 9 shuttle 4, using the 3.46 × (level + shuttles/8) + 12.2 regression.
How accurate is the estimate?
Roughly 10–15% against a laboratory test. It is good enough to track change over time, not to compare two people precisely.
Is 45 a good score?
For a moderately active adult it is good. Trained endurance athletes reach the 60s, and the tool rates 76.2 at level 18 as excellent.
Why does the shuttle number matter so little?
Because each level is worth 3.46 while each shuttle adds only 0.43. Six shuttles move the estimate by 2.6.
What is the 20-metre difference?
The standard test uses 20 m shuttles. A 15 m version uses a different regression, so a score from one is not directly comparable with the other.
